rk is insensitive then why ?

rk is so insensitive that first to humiliate madhu he took padmini and shamsher's live in relation topic.he wants to revenge on madhu then why he married shamsher and padmini.
rk is so insensitive then how he had seen the caring behind shamsher and padmini for each other their is much more where madhu didn't notice till now.
till now rk humiliated madhu nly,he never included anyone of malik's family for taunting madhu.it's easy for rk taunting not only madhu but padmini also by saying see whatever i told on press conference is true, but he didn't .he has humiliated before also padmini on set then what 's the difficult he had to taunt madhu and padmini in this matter.when padmini comes to rk mansion to plead rk he told mrs padmini mallik but didn't taunted her.he only humiliated madhu only.
rk is right kamina bura admi,dil hai ,ki nahi janta hi nahi.more than others woh khud sabse pehle boltha hai that he is bad infront of everyone.he doesn't need to fall in any sahi or galat then the most imp point to be taunted to madhu and padmini by him is not doing.
